As of the end of March 2018, I received the above-mentioned notification.
I have since gone into my directories via SFTP and deleted all rogue directories and malicious PHP files. The offender appears to be a source from Russia, and from the looks of the files and directories, the aim of the hack seems to involve using my storage and site as a repository and possible sender for spam mail of many different kinds, and a possible malware propagator. I run Wordfence. I just want to know if anyone else has had this problem recently. I cannot believe I am paying for managed Wordpress and that this is happening.
Wordfence is a great security plugin, surprised to see attacks in spite of it...
Have you configured Wordfence plugin settings correctly?, Wordfence also provides a report...
Please check the above URL to check your website again...
Looking forward to hear from you
Are you using Managed WordPress?, or cPanel Hosting...
Please do have a look at the above article...
Thanks for your helpful posts.
I am using Managed Wordpress.
I have tried to quarantine, remove files, using WordFence, WebDefender, etc.
The malicious files keep coming back.
I am about to take the site down and reinstall from scratch.
